What Does Map Sensor Do

What Does a Map Sensor Do. The MAP sensor is an input sensor which detects an engine load and provides a signal which is proportional to the sum of vacuum. What does a camshaft sensor do. What is a camshaft position sensor.

What Does A Map Sensor Do

What the MAP sensor does is it assists the engine in figuring out what it needs to have the best combustion possible.

What Does Map Sensor Do. There is 147 P ounds per S quare I nch psi on us at all times at sea level. This data is the basis for fuel delivery and timing control. MAP is an acronym for manifold absolute pressure.

The PCM uses this input as well as others to calculate the correct amount of fuel to inject into the cylinders. The MAP sensor converts engine vacuummanifold pressure to an electrical signal so the computer knows how much load the engine is under. In other words it provides manifold pressure information to the ECU or electronic control unit of the engine.

The MAP sensors primary purpose is to measure the air pressure in the intake manifold to calculate the right air-fuel mixture for your engine. In some vehicles a mass air flow MAF sensor is used. Manifold Absolute Pressure MAP Sensor is the one that converts engine vacuum force into an electrical signal for identifying the load under which the engine works.

Then it translates this pressure into a voltage signal that the sensor feeds to the power control module PCM your cars computer. What Does A Map Sensor Do. In fuel-injected automotive engines a manifold absolute pressure MAP sensor is used to continuously monitor the amount of air flowing into the engine so the computer can calculate air density adjust the amount of fuel to spray into the combustion chamber and adjust the ignition timing.
